In this paper a stochastic model is used to analyse the matching process between skills demand and supply in a segmented labor market. We find the steady state solution of the dynamic system and we address the issue of the necessary conditions for the existence of a steady state and for the...

We explore a base-stock system with backlogging where the demand process is a compound renewal process and the compound element is a delayed geometric distribution. For this setting it is proven in [4] that the long-run average service measures order fill rate (OFR) and volume fill rate (VFR)...

We describe the development of a framework to compute the optimal inventory policy for <p> a large spare-parts’ distribution centre operation in the RA division of the Danfoss Group <p> in Denmark. The RA division distributes spare parts worldwide for cooling and A/C <p> systems. The warehouse...</p></p></p>

We derive a closed-form cost expression for an (R,s,nQ) inventory control policy where all replenishment orders have a constant lead-time, unfilled demand is backlogged and inter-arrival times of order requests are generalized Erlang distributed

We show that well-known textbook formulae for determining the optimal base stock of the inventory system with continuous review and constant lead time can easily be extended to the case with periodic review and stochastic, sequential lead times. The provided performance measures and conditions...

The order fill rate is less commonly used than the volume fill rate (most often just denoted fill rate) as a performance measure for inventory control systems. However, in settings where the focus is on filling customer orders rather than total quantities, the order fill rate should be the...

In this note we comment on whether the cost rate function of Model 2 of Rosling (2002) is exact

Most organizations can manage reverse logistics operations strategically but very few of them have successfully streamlined material flow of the return process and information due to lack of integration within the overall process. This research aims at analysing complete reverse logistics...

Aware of the importance of developing new alternatives to improve the performance of the companies, our purpose in this paper is to develop a medium term production planning model that deals with the concepts of Partnership and Reverse Logistics. Our model takes advantage of the synergies of...

Nowadays, the Reverse Logistics field is becoming very important. On one hand, laws are imposing companies to be responsible for the contamination made by their products. On the other hand, companies have discovered the profits derived from a good Reverse Logistics process. This paper is the...
